Abstract
A novel meso–macroporous bioglass has been synthesized based on a sol–gel technique. This method used mushroom stalk as macroporous template and EO20PO70EO20 as the mesoporous template. The final sample has copied the macroporous structure of the plant template, precisely. Ibuprofen was used as the model drug, and the drug loading and release test indicated the loading amount of the sample could reach 33.59 wt% and the releasing amount closed 75 wt% after 48 h. The excellent biomineralization and bioactive are also confirmed in vitro tests. It takes only 4 h to induce the formation of hydroxyapatite. Notably, the biocompatibility assessment confirmed that the obtained materials presented good biocompatibility and the enhanced adherence of HeLa cells. The exquisite mesoporous structure of the sample would be propitious to storage and transport guest molecule, making the hierarchical porous materials have more distinctive performance and application on bone tissue regeneration and drug delivery, etc.
